i To all whom it. may concern Be it known that I, OLIVER E. MAYNARD, acitizen of the United States, and a resident of Kane, in thecounty ofMcKean, State o-fPennsylvania, have invented certain new and usefulImprovements in Glass- Drawing and Take-Down Apparatus, o1 which thefollowing is a full, clear, and exact description. reference being hadto the accompanying drawings, in which- Figure 1 is aside elevation ofone form of apparatus embodying my invention. Fig. 2 is an end elevationof a portion ot the same. Fig. 3 is a. vertical section taken on theline 3--3 of Fig. 2. Fig. 4 is a sectional view taken on the same lineas Fig. 3, but with certain parts omitted and with other ot the parts ina different position. Fig. 5 is a section on the line 5-5 of Fig. 1.Fig. 'G is a view partly in plan and partly in section oit an operatingdevice. Fig. is a section on the line 7--7 of Fig. 1, Fig. 8 is a detailview hereinafter referred to, and Fig. 9 is a perspective view of theelevator cage.

My invention has relation to glass drawing and take-down apparatus, theobject being to provide, in combination with glass drawing apparatus,means of simple and effective character for engaging the drawn articleand placing it upon a suitable support.

To this end, my invention consists in the combination with glass drawingapparatus' having mechanism tor intermittently draw ing glass articles,of a take-down apparatus which is movable toward and from the drawnarticle and which is arranged to engage the same between the bait of thedrawing apparatus andthe glass holding receptacle and remove the sameinto the desired position.

The nature of my invention will be best understood by reference to theaccompanying drawings, in which I have shown one embodiment thereof, andwhich will now be described, it being premised, however, that variouschanges may be made in the details of construction and arrangement ofthe parts without departing from the spirit and scope of my invention asdefined in 4the appended claims.

In these drawings, the numeral 1 designates a suitable supportingframe-work which is built above a pit' 2, in which is located anair-jack or other suitable littingy device 3.

f1 is a clay block carried by the lifting device and which supports aglass pot or receptacle 5, the jack being arranged to raise and lowerthe block 11, so as to bring the pot 5 into the proper'position fordrawing.

(5 designates a wall forming a kiln for keeping the pot heated.

The 4frame-work 1 is provided with suitable ways '7, upon which ismounted a vertical movable drawing eage 8. This cage is provided withsuitable guides 9 (see Fig. 9) which are adapted to engage the ways 7'during the vertical movements of the cage. It is also shown as having aseries of fork like projections 10 (see Fig. 9), the openings 11 betweenthe prongs of the forks being adapted to receivea blow pipe or bait stem1Q. '.lhis stem is preferably provided with an enlargement or collar 13,for the purpose of supporting it on the upper of the three forks 10. Atits lower end it is provided with a bait 11, which is adapted to belowered into the glass pot 5 in the usual manner in drawing glassarticles.

The blow `ipe or stem 12. is telescopically connected Wlth a pipe ortube 15, which is {xedly supported on the upper portion of the frame 1.lIn the drawings I have shown this pipe 15 as being connected by pipes1G and 1'7 with the lower end of a cylinder 18, which is designed tohold air or gas under pressure, this air or gas constituting a blowingmedium for the cylinder. The necessary blowing medium may, however, beprovided in any suitable or well-known manner. The pipe 16 is shown ashaving an extension 19 which also communicates with the pipe 17, andthis extension has a valve 20 which opens in one direction to permit airto bc forcedy into the cylinder when the pressure within the latter isless than the atmospheric pressure. The cylinder is provided with atelescoping piston section 21, which is ixedly mounted on a frame 22connected with the main frame l; while the piston section 21 isreciprocatingly mounted thereon and is designed to recipcate with thedrawing cage, but to move 1n the opposite direction to the cage. Forthis purpose the cylinder 21 and the cage are connected by a chain l' orcable 23, which passes over pulleys 24, being liXed at one end oftheframe 22. The cage-is provided with -a flexible connection 25passingupwardly over a pulley 26 and connected with a sprocket chain 27.This chain passes around a sprocket wheel 28 which actua-tes the chain.This sprocket wheel is connected with a`gear 29, which, in turn, mesheswith a gea-r or pinion 30 on a shaft 31, operated by a motor 32, asshown in Fig. 6. A clutch 33 is provided forcontrolling the connectionbetween the sprocket 28 and the gear 29. This 4clutch is normally forcedinto locking position by means of a spring 34 'and can be pulled out ofthat position by a lever 35 which is controlled by one or moreelectro-magnets 36. The magnetsare operated by an electric circuit 37;and. the

motor by a circuit 38, the latter having a controller 39. The chain 27pa'sses around the sprocket wheel 28 and is connected at its oppositeend with a flexible connection 40. The latter passes over a pulley 41 onthe frame 1 and around 'the pulley 42, which is preferabl journaled onone of the guides This pu ley 42 is located below the'lowermost positionof the drawing cage; and the connection after passing around saidpulley', is secured at its end to the vsaid' cage.

The operation of the motor will cause the cage to either rise or fall.`The connection 40 is also arranged to operate a traveling carriage 43,which is mounted to run 'on an inclined track. This track is shown asconsisting of the two `rails 44 and 45 at ditlerent elevations, thecarriage 43 having langed wheels 46 and 47 which run under the track 44and over the track 45, respectively. lThe carriage also carries aplurality of sheaves48 and 49, the sheave 48 being located above thesheave 49 and at the rear of it.

The-carriage 43 has mounted thereon a frame 50which is provided withparallel rails 51, one located in front of the other, one `of the railsrunning under the sheave 48 and the other over the sheave 49. Thecarriage 43 also 'has sheaves 52| located above the front rails 51 andin line with the slieave 49, whereby the rail which passes between thesesheaves and the sheave 49 will be secured in position between them. Theframe 50 has projecting arms 53 provided with rests 54 for receiving thedrawn glass cylinder. The carriage is also provided with a frame 43a onwhich is mounted a sheave 43b and a pivoted finger 43c (see Fi 8). Whenthe linger 43c is in the position s own in Fig. 8, the cable 40 can passin either'direction without moving the carriage; but when thev parts aremoved to the left, the cable is clamped betweenthe sheave 43b and thefinger 43c and the carriage will be moved with the cable. The movementof the cable 40 in one direction will automatically operate this clamp.

When the cylinder is ready to be cut 0E and taken down, the operatormoves the take-down carriage 43 up the inclined track, and when thecarriage is at the upper portion of the track he tips it into suchposition that the rails 51 are in the vertical position shown in dot-tedlines iii-Fig. 4. At this time the rests 54 engage the cylinder of glassso that when tipped back they support it down the inclined plane, thestem 12 being disengaged from the pipe and forks 10. As the endlessiexible connection above described moves longitudinally when thecylinder lhas been cut loose, it operates the finger 43cand moves thecarriage and the frame supported by it down the inclined tracks untilthe carriage reaches a position at the lower end of the track. i Thetake-down device is designed to transfer the cylinder of glass from t eposition 1n which it is made, to what is called the capping-off horse.In the drawings 1 have shown this horse (see Fig.' 1) as consisting of aframe 55, provided with a series of vertical guides 56 carrying slidingrods 57. Each 'rod 57 is provided with arest 58 at the upper endthereof, and also has a rack 59 meshing with the segmental gear 60. Eachof these gears is connected with an actuat' ing rod 61, whereby allthegears may be turned upon their pivots at the same time by a longitudinalmovement of the rod. To elect this movement of the rod, it may-beprovided with an operating handle 62 having the usual pawl and rackholding devices 63 and 64. When the glass cylinder is suspended over therests 58, the handle 62 is operated to raise the rests so that they aremoved upwardly into engagement with the cylinder and thus lift the samefrom the rests y54. The latter can then be lwithdrawn and the cylinderlowered.

1n the drawing operation, a blow pipe or bait stem y12 is heated andplaced in p osition with respect to the cage, its telescopic partbeingproperly fitted so as to prevent the escape of air. The clutch 33 isthen released and the bait is lowered into the glass. The motorl 32 isthen started so as to draw the cage and pipe upwardly. As the cageascends, thepiston-of the air cylinder is lowered, thus forcing airthrough the pipes 17, 16, 15 and 12 into the interior of the glasscylinder which is being drawn. Tlie motor 32 is preferably started at alslow rate of speed, which is gradually increased by means of thecontroller 39. When the cage has attained the proper height to give thecylinder the desired lei'igth, the take-down carria-ge is run up behindthe cylinder in the manner before described. When the motor 32 isstopped and the clutch 33 released by the operation of the circuit 37and the magnets 36, the sprocket wheel 28 becomes an idler. The drawingcage will then start down by force of gravity, drawing up the piston orsection 21 so as to fill the cylinder 18 with air. The clutch shown inFig. 8 is then freed from the cable between the rails 44 and 45; and thetake-down carriage 43 runs along the track toward the motor and carriesthe cylinder with it. A suitable -device may be employed for severingthe connection between the articles and the glass in the pot adjacent tothe drawing point.

The advantages of my invention result from'the provision of meanswhereby the machine itself can be made to take down the cylinders, thuslargely dispensing with hand operation to perform these steps.

As before stated, I do not limit myself to the construction andarrangement of the parts, as herein shown and described, thus anysuitable means may be rovided for supplying the cylinder with air whileit is being drawn; the construction of the drawing carriage may be ofany usual or suitable character capable of supporting the blow pipe inthe manner described, so that the latter can be disengaged from itsconnecting pipe in lthe taking-down operation; the manner of operatingthe take-down carriage, together with the details of constructionthereof may be varied and any suitable capping 0E arts may be employed.
